:PIPE CONSTRUCTION.

To all 'whom/15 may concern.'

Be it known that I, J osEPH W. WELCH, a citizen of the United States, residing at Ogden, in the county of Weber and State of Utah, have invented certain new and useful Improvements in Pipe Construction; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pipe construction, and it relates especially to certain improvements in connection with my pending application #691,921, iled April 19, 1912.

An object of the invention is to provide certain improvements of construction that will render the pipe sections perfectly interchangeable with each other and adapted to be quickly and easily Vconnected with the pipe sections and couplings illustrated in said pending application.

Another object ofthe invention is to provide a pipe section of this character, the end connectionsof which are interchangeable with each other. f

A still further 'object of the invention i to provide a pipe section of this character, which may be assembled by inexperienced and inexpert workmen, without the necessit-y of using tools other than ordinary wrenches, and a still further object is to provide a Vpipe of this character, which is entirely non-lealrable.

With these objects in view the invention consists in the improved construction, arrangement and combination of parts of :a device of the character specified, which will be hereinafter fully described and afterwardV specifically claimed.

In the accompanying drawings Figure 1 Y is a top plan view of the adjacent ends of two pipe sections and their connections constructed in accordance with my invention. Fig. 2 is a vertical sectional view in the axial plane of the pipe'sections .andthe connections on the line 2-2 of Fig. 1. Fig. 3 is a sectional view taken on the line 31-3 of Fig. 2. Fig. 4 is a sectional view taken on the line L1---1 of Fig. 1. Fig. 5 is a fragmental sectional view illustrating a modified Specification of Letters Patent.

form of the invention, and Fig. 6 is a fragmental sectional view of another modified form of the invention.

Referring to these drawings in which similar reference characters indicate similar parts throughout the several views, t-wo similar counterpart pipe sections 10 are provided with beads 11 and corresponding grooves 12, and into the grooves 12 are tted beads 13, which are formed on a clamping ring 14E. A. pair of outer clamping rings 15 are provided with peripheral grooves 16, which are fitted upon the beads, 11' and each ring or tightening band 15 is provided with screw bolts 17 formed on its ends, which extend through apertures 18 in a clamping head or block 19, and on opposite sides of the head 19 are nuts 20, by means of which the bands 15 may be clamped tightly in position upon the respective beads 11. The` block 19 is formed with grooves 21 which it upon the beads 11 between the ends of the grooves 16.

The adjacent edges of the respective pipe sections 10 are slightly spaced apart for the reception 'of clamp bolts 22 (see Fig. 4), and the adjacent edge portions of said sections i areprovided with beads 23 and corresponding grooves 24. A longitudinally curved clamping vstrip 25 ts over the beads 23, while a longitudinally beaded clamping strip 26 fits into the grooves 24; so that when the nut is tightened upon bolt 22, the clamping strips 25 and 26 coact therewith for tightly and securely clamping the adjacent edges of the pipe section 10, so as to form the same into a ring or cylinder. The head or block 19 is provided with recesses 27, into which are tted the respective ends of the clamping strips 25.

The pipe sections 1() may be of any desired and convenient length and diameter, but the construction described is particularly applicable for pipes of large dimensions, such as iumes and conduits for mining, irrigating, dredging etc., but it is more particularly useful, convenient and economical when the circumstances are such that the pipe, flume or conduit is to ybe transported for a considerable distance by private conveyances, such as wagons, carts, etc., when it becomes especially desirable to nest the pipe sections,

thereby reducing their bulk to the minimum. This may be done in an obvious manner before the clamping strips 25 and 26 are applied, and before the clamping bands and block 19 are applied, and it is obvious that the rings 15 can also be nested and rendered compact for shipment.

' It is obvious that the several beads, grooves, and other elements of the integral members of the pipe or flume may be formed at a suitable factory, so that the necessity for subsequently machining, cutting, punching, boring or bending any of the parts is en` tirely eliminated, during the operation of assembling said integral members.

The pipe or flume is assembled as follows: First, the nuts 20 are unscrewed, but not removed from the bolts 17, the pipe sections 10 are then reduced in diameter, by causing their adjacent ends to lap until the beads 11 are seated in the grooves 16, and the nuts on the bolts 22 are then loosened, so that the strips 25 and 26 may be slid into place on one of the sections 10, during which operation the bolts 22 slide between the adjacent edges 28, until an end of the strip 25 is seated in one of the recesses 27 whereupon the ring 111 is seated into place, and then the other clamping strips 25 and 26 are slid into place on the other side of the ring and on the other section 10, and then the nuts 22 are tightened, 'for clamping these strips 25 and 2G upon the adjacent edges 28, and the nuts 2O are then tightened, for clamping the adjacent ends of the respective sections 10 upon the internal ring 14. Other sections 10 and their Y clamping members are attached in the same way, without the removal of any of the bolts lor nuts, thereby effecting a great saving of time, andavoiding the loss or misiitting of said bolts or nuts, and at the same time allowing thepipe or flume to be assembled by entirely inexperienced persons. Owing to the spaces between the edges 28 communicating with the spaces between the adjacent ends of the pipe sections, as indicated at 29, an opening results, which would allow the pipe to leak at 29, and inY order to avoid leakage at this point,I provide the block 19 with a cent-ral aperture 80, communicating with the opening 29. Through the opening 30, I may pour melted lead, sulfur, or other suitable material for closing the opening 29, having iirst applied clay or the like for preventing the melted material from escaping from under the block 19.

In Fig. 5 I have illustrated a modiiied form in which two internal rings and one external clamping ring are employed as indicated at lil and 15 respectively, while in Fig. 6 is illustrated another modiiied form in which the internal clamping ring is provided with grooves 13, in lieu of the beads 13 in Fig. 2. In this view, the pipe sections 10 constitute a modified form of the pipe sections 10, while the clamp rings 15ab iit int-o the external peripheral grooves of said pipe sections. Y Y

It is obvious that the same general principle applies in the several forms, and Vit is also obvious that I have provided a device of this character which is ullycapablerof attaining the foregoing objects, and ina thoroughly practical and eiiicient manner.

I do notV limit my invention to the exact details of construction, combination and arrangement of parts, as herewith'illustrated and described, but my invention may only;

be limited by a reasonable interpretation of the claims.. Y
